Lnw-80 restore

[grayfox386]

iam still restoreing an lnw-80 i have a working power supply and i have replace most of the ram and cleaned the boards my problem is the ceramic rom on the board is geting very hot and i feel it may be damaged so iam replace it with a level 2 rom set from a trs-80 iam still seeking a list of ics used in the mother board to make replaceing them easier so far i have no video output but i think thats becuz of the missing chips in the clock circuit
any help will be nice thanks for all the hel so far
